Head to the Syrush Estate Heroic Area and look for the large purple-hued cave entrance to the Ruur Kilik Burrows around X: 2376, Y: 2354.

Go east through the tunnels until you reach a large boulder with a Blast Pack embedded within. Right click the Blast Pack with the Red Detonite Actuator in your inventory and it will clear a hole in the boulder large enough for you to fit through. The datacron is located on the other side of the newly-cleared space between the boulders.
